v\u00e1lvula de esfera flutuante<\/a> e uma v\u00e1lvula de esfera fixa de baixa temperatura. \u00c9 utilizada para cortar ou ligar o meio de baixa temperatura cuja temperatura m\u00ednima na tubula\u00e7\u00e3o n\u00e3o seja inferior a 196 graus Celsius negativos.<\/p>\nA fim de evitar a falha do selo de veda\u00e7\u00e3o da haste sob condi\u00e7\u00f5es de baixa temperatura, a v\u00e1lvula esf\u00e9rica de baixa temperatura adota um projeto de estrutura de pesco\u00e7o longo.<\/p>\n
O assento \u00e9 projetado com uma fun\u00e7\u00e3o de al\u00edvio autom\u00e1tico da press\u00e3o para parar o fluido na v\u00e1lvula. O aumento anormal da press\u00e3o devido ao aumento de temperatura requer um controle rigoroso da composi\u00e7\u00e3o qu\u00edmica do material e das propriedades mec\u00e2nicas, tais como a resist\u00eancia ao impacto a baixas temperaturas.<\/p>\n
Caracter\u00edsticas:<\/strong>
\n1. Esta v\u00e1lvula \u00e9 uma v\u00e1lvula de esfera flutuante de passagem plena com estrutura compacta, bela apar\u00eancia e pequeno coeficiente de resist\u00eancia ao fluxo.
\n2. A superf\u00edcie de veda\u00e7\u00e3o \u00e9 feita de fluoropl\u00e1stico, os materiais do par de veda\u00e7\u00e3o s\u00e3o emparelhados razoavelmente e a vida \u00fatil \u00e9 longa.
\n3. A esfera e a sede da v\u00e1lvula PTFE s\u00e3o hermeticamente seladas e combinadas com a fun\u00e7\u00e3o de vazamento zero, e podem compensar automaticamente o erro causado pelo desgaste usando deforma\u00e7\u00e3o pl\u00e1stica, e alcan\u00e7ar um bom desempenho de veda\u00e7\u00e3o.
\n4. V\u00e1rios padr\u00f5es de flanges de tubos e tipos de superf\u00edcie de veda\u00e7\u00e3o de flanges podem ser selecionados. Acionamento manual, acionamento por turbina, el\u00e9trico, pneum\u00e1tico, hidr\u00e1ulico e outros m\u00e9todos de acionamento est\u00e3o dispon\u00edveis para atender \u00e0s diferentes necessidades dos usu\u00e1rios.<\/p>\nUtiliza\u00e7\u00e3o:<\/strong>
\nA v\u00e1lvula de esfera criog\u00eanica \u00e9 utilizada principalmente em equipamentos qu\u00edmicos como etileno e g\u00e1s natural liquefeito.<\/p>\nTalvez voc\u00ea tamb\u00e9m queira ler:
